摘要: 对比分析常规进近与RNP AR 进近的飞机噪声影响,旨在分析RNP AR 进近是否具有减噪优势。根据飞机类型、转弯时间的差异把常规进近分散的飞机航迹合理归纳为多组别航迹,替代标称航迹输入INM 计算噪声。替代后更准确地评估飞机噪声影响,并反映两种程序的噪声影响差异。结果表明,实施RNP AR进近飞机噪声的总影响面积没有减少,个别噪声等级的影响面积还可能增加。转弯区域噪声影响范围沿标称航迹向远离机场方向延伸,标称航迹两侧影响宽度明显减小。

Abstract: To analyze whether it has the advantages to reduce the noise of RNP AR APCH by comparing the aircraft noise effects of normal approach with RNP AR approach. The dispersive aircraft tracks in normal approach can be classified into several groups by the difference of aircraft types and turning times. Then the multiple tracks are input instead of nominal track to INM for calculating the noise. A more accurate assessment of aircraft noise impact can reflect difference between the two procedures after replacement. Result shows that total impact area of aircraft noise is not reduced, the impact area of individual noise levels is possible increased, and the range of noise in the turning region extends along the nominal flight path away from the airport and the influence width of nominal track is obviously reduced by implementing RNP AR APCH.
